It makes sense to allow people to hide their real/legal name, while showing displaying their username, when donating. So they can get sweet sweet internet cred, without doxxing themselves.

This has come up a few times, most recently in this social post

If that is not possible for some reason, perhaps it would be worth adding a note to to the donation page that even if you anonymously donate, you still get to set a ListenBrainz animated banner (I assume as long as you enter your username into the username field?)

P.S. if this is implemented we should consider having legal name set to anonymous by default/a pre-checked field - showing the legal name is pretty intense.
